关于螺旋兰（Spiranthes australis）

Austral Ladies' Tresses is a small terrestrial orchid with tiny pink flowers spiraling up a slender stem, in roughly equal right- and left-turning forms, including rare white variants — a plant best suited to experienced growers.

开始养护螺旋兰（Spiranthes australis）前需要了解的7件事

1. 1Sun and Airflow Matter

   Austral Ladies' Tresses does best outdoors in a sunny spot with good air circulation. Avoid harsh late-afternoon sun, but give it as much daylight as possible for healthy growth.

2. 2Don't Let It Dry Out

   In the wild it grows in damp lawns and grassy banks, so it dislikes extreme dryness. Water thoroughly once the soil surface dries, and avoid letting it stay dry for long periods.

3. 3Balance Drainage and Moisture

   Soil that's too dry or constantly waterlogged both weaken the plant, so choose a mix that balances drainage with moisture retention. A commercial alpine or wildflower potting mix is a good starting point.

4. 4Avoid Repotting When Possible

   The roots of this orchid live in partnership with fungi in the soil. Disturbing that relationship by repotting can cause the plant to die after flowering, so the basic rule is to avoid repotting whenever possible.

5. 5Adjust Care by Season

   Native throughout Japan, it handles both heat and cold well and keeps its leaves through winter. Give it good sun all year and don't let the soil dry out completely. Sudden changes in environment can stress the plant, so introduce changes gradually.

6. 6Check the Spike and Leaves

   When choosing a plant, look for a sturdy flower spike and firm, healthy leaves. Part of the fun is noticing individual variation — whether the spiral twists clockwise or counterclockwise, or spotting the occasional white-flowered form.

7. 7Renews Itself by Seed

   Individual plants are short-lived, and the species keeps going by self-seeding and renewing itself generation after generation. Keep this life cycle in mind and take a long-term view when growing it.
